Siggi's tavern was a place of business that served alcoholic beverages, located in the mining settlement of U'ronoh on the world of E'ronoh. At least one employee worked there as a server of drinks. In the year 382 BBY, a ceremony of remembrance took place inside the tavern, honoring two deaths from the village; many residents of U'ronoh gathered to grieve, and they were accompanied by princess Xiri A'lbaran of E'ronoh and future ruler Phan-tu Zenn from the nearby planet of Eiram. After family members shared memories of the deceased, the atmosphere improved, and people engaged in musical performances and movement.
The Jedi Gella Nattai ordered a cocktail from the bartender, but she found its strong flavor challenging to consume. While present in the tavern, she had a conversation with Iana Percei, who was the law enforcement officer of U'ronoh, as well as a person named Kala. Soon after Percei joined the dancing, Nattai departed. Later that evening, precipitation began to fall, an unusual occurrence on the arid planet that caused everyone in the tavern to step outside and observe.
Siggi's tavern was featured in the 2022 book Convergence, penned by Zoraida Córdova as a component of the Star Wars: The High Republic series' second phase.
